Tyrannosaurus-Rex is probably the most well known dinosaur in the world. Discovered in 1905 by Barnum Brown, the Tyrant Lizard King has been terrifying and intriguing people around the world ever since. Standing 20 feet tall and weighing 7 tons, Tyrannosaurus-Rex was the largest predator of the Late Cretaceous. When it was first discovered, the T-Rex was put into an upright position. But, paleontologists soon realized that this posture would have dislocated the T-Rex’s hip bone. They then re-positioned it with a straight back. This position is yet to be disproved. The Tyrannosaurus-Rex had great senses. It was recently believed that the T-Rex’s vision was based on motion. But, this is not true. The T-Rex’s vision is just as good as ours. Besides, its nose would’ve made up for it. The nose of a T-Rex could smell a meal from miles away. Many scientists believe that the T-Rex was a scavenger. It was not very fast, because the femur is longer than the pelvis. Its arms couldn’t even come together; they were the size of a man’s. Plus, the teeth were designed for bone crunching, not flesh ripping. This is good evidence, except that these are the makings of an ambush-er. Some people think that it would have surprised its prey as opposed to chasing it. The original King of the Beasts has many mysteries that are yet to be solved. Maybe it wasn’t a hunter after all? Maybe it was a cunning creature like the fox, instead of the monster the world has learned to love. Whatever it turns out to be, we will always remember it as Tyrannosaurus-Rex, the Tyrant Lizard King.

As the largest cephalopod in the world, the colossal squid reaches about 33 feet in length and weighs about 1,091 pounds.

Colossal Squid

Mesonychoteuthis hamiltoni

Range: oceans surrounding Antarctica

Diet: Patagonian toothfish

Life span: no one knows; only one colossal squid has been seen alive.

As the largest cephalopod in the world, the colossal squid reaches about 33 feet in length and weighs about 1,091 pounds. Many colossal squids are thought to live in the extreme depths of the ocean. There is proof of this; many beaks and tentacles belonging to the beast have been found in sperm whales’ stomachs, considering they have only one predator- the sperm whale. For now, we have only seen 4. Research is continuing to be done, and soon there will be news of the colossal squid around the world.

The reason that this squid is so large is because of something called deep sea gigantism, which can be found in the giant isopod, giant squid, and giant tube worm as well. This is an adaptation to the extreme pressure in the deep sea; every 33 feet is another atmosphere of pressure under the sea.

Many people mistake the colossal squid for its cousin, the giant squid. Because the colossal squid is larger than any other cephalopod, it should not be mistaken for its smaller and better known version, the giant squid.
